Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed August 24, 1905. Serial No. 275,553.

To all whom it may concern.-

Be it known that I, HARRY CooMnns HEN- SEL, a citizen of the United States, and a resi dent of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Type-Distributing Mechanism, of which the following is a full, clear, and exact description.

The invention relates to an improvement in mechanism for distributing separate type of that class in which the type are distributed into pockets, each pocket having a characteristic form corresponding to the form of the particular type which it is intended to receive and the distribution being effected by a holder rotatin or otherwise moving over the part in whic the pocket is formed. In such machines the rotating part carrying the type for distribution is formed with a number of pockets in which the type are placed, and the machines are arranged so that these pockets register exactly with the pockets in Which the type are distributed. When this registry occurs, the type, if it registers with the form of the pocket over which it has been placed, will drop into the pocket and the step-bystep motion of the moving part is re sumed, carrying other type on to the next pocket. Difficulty has been experienced, however, in bringing about the exact registry of the pockets, and this results in a failure of the type to drop, the crushing of the type, and other more or less disastrous results.

The object of my invention is to overcome this disadvantage and to insure exact registry of the pockets, and consequently rapid and reliable distribution of the type. I attain this end by providing mechanism which gives the moving part of the type-distributing mechanism not only its usual step-bystop movement from pocket to pocket, but one or more additional and very slight movements when the pocket is reached, so that if when the moving parts halt at a pocket registry is not then exact a slight additional movement or movements is given to the moving part, whereby to bring the pockets into exact registry. These additional movements are necessarily minute, and the interval be tween movements is arranged to be sufficient to allow the type to drop freely.

The invention resides in certain special features of construction and combinations of parts, which will be fully set forth herinafter and particularly pointed out in the claims.

Reference is had to the accompanying drawings, which illustrate as an example the preferred manner of carrying out my invention, in which drawings Figure 1 is an elevation of the upper part of the type-distributing machine of the class hereinbefore mentioned and showing the cam for rotating the section in which the d1stributed type are placed prior to distribution. Fig. 2 is a side elevation of the cam. Fig. 3 is an end or face view thereof. Figs. 4 and 5 are diagrams illustrating the operation of the two sections of the distributing device, and Fig. 6 is a developed view of the cam.

10 indicates the movable pocketed part of the machine. form and provided with pockets extending axially of the cylinder around the sides thereof, the pockets being capable of accommodating the type of any character. The lower section, or that into which the type is distributed, is shown diagrammatically at 11 in Figs. 4 and 5. This is also usually constructed in cylindric form, with the pockets extending axially around the sides; but said pockets are provided with wards, the wards of each pocket having a distinct or characteristic form, so that the type which are nicked corresponding to the wards will fall only into the pockets intended therefor, the two cylinder-sections engaging snugly against each other and the upper section rotating around the lower, so that the pockets of the upper section are successively placed into registry with the pockets of the lower section. The upper section, according to the type of the machine here illustrated, is driven by a cam 12, (see Fig. 1,) which engages studs 14, formed on or fastened to said section 10, the cam being of such form as to give the section a step-by-step movement, so that this movable section 10 dwells slightly each time that the pockets come into registry, this dwell being for the purpose of allowing the type time to drop.

In applying my invention to the form of the machine here illustrated I so plot the cam 12 that it gives to the rotating element 10 not only its usual step-by-step movement, but at the end of each movement or step the cam gives to the moving part a further or very slight movement, or, if desired, a plurality of these further or what might be termed secondary movements.

This is usually cylindric in Referring to Figs. 4 and 5, let it be assumed that Fig. 4 represents diagrammatically the relative position of the two sections of the distributer at the end of a step or primary movement, and, as there shown, the pockets have not gone into exact registry. The moving part dwells for an instant in this position, and the type does not drop, since registry has not been established. Then the brief secondary movement or movements, if desired, takes place and the parts assume the position shown in Fig. 5, in which absolute registry has been secured, and such of the type as correspond with the wards in the pockets of the stationary section drop freely into distributed relation.

The precise form of the improved cam is in no way material. Figs. 2 and 3 show a manner in which an old cam may be remodeled to follow my invention, this being done by attaching to the face of the cam plates 12, which change the profile sufficiently to bring about the secondary movement described. The cam in Figs. 2 and 3 is modeled to impart two primary steps to the moving part 10 for each rotation of the cam, and, as shown in these views, two plates 12 are attached to the cam, so that at the end of each primary movement or step a secondary step will be given. In Fig. 6 the cam of Figs. 2 and 3 is shown as developed or rolled out onto a plain surface. In this view 1.2 represents the part of the cam which. imparts the first primary step. 12 represents the straight part of the cam allowing the moving section 10 to dwell, 12 represents the inclined part of the cam, which imparts the first secondary step which follows immediately after the primary step, and 12 indicates the straight part of the cam following the part 12 which part 12* allows a further and more prolonged dwell of the moving section 10. From the point 12 the cam continues with surfaces corresponding exactly to the surfaces 12*, 12 12 and 12 above described, it being understood that the cam illustrated is of that form which gives the moving section 10 two primary steps to one revolution of the cam. It is also obvious that the sections 12 of the cam giving the secondary step may be made plural in number, so as to impart a plurality of secondary steps without in any way departing from the essential principle of my invention.

Having thus described the preferred form of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. In a type-distributing mechanism, the combination of two pocketed sections, one of which is movable relatively to the other to successively register its pockets with the pockets of the other section, and a means for giving said movable section a stepbystep movement, said movement being coniposed of relatively long or primary steps advancing the pockets of the movable section into registry or approximate registry, and each long or primary step being followed by a relatively short or secondary step to insure the registry of the pockets.

2. In a type-distributing mechanism, the combination of two pocketed sections, one of which is movable relatively to the other to bring its pockets successively into registry with the pockets of the second section, and a cam coacting with the movable section serving to impart thereto a step-by-step movement, the cam having a relatively long or primary step followed by a relatively short or secondary step, and the long or primary step of the cam serving to move the pockets of the movable section into approximate registry with the pockets of the other section, and the short or secondary step insuring registry of the pockets.

3. In a type-distributing mechanism, the combination of two pocketed sections, one of which is movable relatively to the other to bring its pockets successively into registry with the pockets of the second section, and a cam coacting with the movable section serving to impart thereto a step-by-step movement, the cam having a relatively long or primary step followed by a relatively short or secondary step, and the long or primary 9 step of the cam serving to move the pockets of the movable section into approximate registry with the pockets of the other section, and the short or secondary step insuring registry of the pockets, and the cam having its said steps separated by a straight portion causing an interval between. the said movements of the movable section.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
